Qos for video Conferencing

Aug 10, 2006 7 Replies

I am the IT Admin for a company just getting off the ground. That being said, the IT budget is relatively limited (extremely limited actually). My superiors are trying to go the cheap route in most aspects (as you may have been able to see if you have read any of my previous posts). I am looking at a NetGear 48 port switch for just under $300 but it is unmanaged and provides no QoS, VLANs, etc. Down the road, they want the ability to use video conferencing over the T1. Will it be a large problem without being able to implement QoS on the switch? Currently, only 35 of the 48 ports will have traffic and it will be utilizing connectivity for Internet and to our lone server running a whole slew of services included with Microsoft SBS.



Thanks.

No one has responded yet and you seem very knowledgeable. I am trying to convince my company to purchase a Cisco ASA instead of this cheap thing.

Thanks.

Is your T1 a private T1 (Frame, P-to-P, MPLS) to another branch? What are the routers on both sides?

For a small company, I have found that QoS on the switch is optional but QoS on the router is mandatory. You may be able to live without it, depending on your traffic flow.

Rob,

Thanks for your response. Our T1 is simply an Internet T1 as we are the only branch. However, we have outsourced a large ecommerce project to three seperate companies and meet with them frequently via conference calls. My thinking was at this time with a 48 port switch with how small we are there will be no congestion in the switch at this time. The router is QoS capable.

Thanks for your response.

This isn't really enough information overall. Your limiting factor in bandwidth is going to be the T1. I'm assuming this 48 port is

10/100Mbps based on the price. Think of it this way... You have 1.5 Mbit T1 to the Internet. You have 100Mbps dedicated switching on each port internal. If you're talking to people over the T1, where do you think this bottleneck is going to occur first? :)
